Description

Technical Field

[0001] The utility model relates to a seismic wall, in particular to a seismic wall with a friction damper and a buckling restraint combined device. Background Art

[0002] Seismic resistance of walls has always been a research hotspot in the construction industry. Under the action of an earthquake, walls are prone to damage and are not easy to recover after the earthquake. With the development of prefabricated buildings, not only the construction period is shortened, but also further research has been carried out on the seismic performance of walls: by splicing upper and lower seismic connecting walls, the connection area is damaged while the joints do not fail; however, due to the complex connection in the core area of the joints, the joints cannot be replaced after failure. Therefore, how to ensure that the seismic wall has good energy dissipation capacity is crucial and remains to be further improved. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a seismic wall with a friction damper and a buckling restraint combined device, which can ensure that the components have sufficient energy dissipation capacity, the joints can be replaced after failure, and the cost is saved.

[0004] The technical solution adopted by the utility model to solve the above technical problem is to provide a seismic wall with a friction damper and a buckling restraint combined device, including an upper seismic connecting wall and a lower seismic connecting wall. Structural columns are arranged on both sides of the upper seismic connecting wall and the lower seismic connecting wall. Among them, a reserved gap is formed between the structural columns and the upper seismic connecting wall and the lower seismic connecting wall as a displacement space under the action of seismic load. Masonry secondary structures are arranged on both sides of the structural columns. The upper seismic connecting wall and the lower seismic connecting wall are connected to the connecting steel plate through anchor bars, and the connecting steel plate is connected to the dog-bone plate through bolts.

[0005] Furthermore, the upper seismic connecting wall and the reinforced concrete beam are connected into a cast-in-place integral through steel bars, and the lower seismic connecting wall and the lower reinforced concrete beam are connected to form a cast-in-place integral.

[0006] Furthermore, the reserved gap is filled with a foaming agent to form a foaming filling area, and a wire mesh is arranged in the foaming filling area for connection.

[0007] Furthermore, the bolt holes on the connecting steel plate are oval.

[0008] Furthermore, the bolt holes on the dog-bone plate are oval.

[0009] The utility model has the following beneficial effects compared with the prior art: The seismic wall with a friction damper and a buckling restraint combination device provided by the utility model consists of anchor bars, energy-dissipating connecting steel plates, and dog-bone plates to form the friction damper and the buckling restraint combination device, ensuring that the component has sufficient energy-dissipating capacity.

[0020] The following further describes the utility model in conjunction with the drawings and embodiments.

[0021] Figure 1 It is a schematic structural diagram of the seismic wall of the utility model with a friction damper and a buckling restraint combination device.

[0022] Please refer to Figure 1, the seismic wall with a friction damper and a buckling restraint combined device provided by the present utility model includes a seismic upper connecting wall 4 and a seismic lower connecting wall 5. The seismic upper connecting wall 4 and the reinforced concrete beam 1 are connected by steel bars to form a cast-in-place integral body. The seismic lower connecting wall 5 and the lower reinforced concrete beam 1 are connected to form a cast-in-place integral body. On both sides of the seismic upper connecting wall 4 and the seismic lower connecting wall 5 are construction columns 2. Among them, a reserved gap 3 is formed between the construction columns 2 and the seismic upper connecting wall 4 and the seismic lower connecting wall 5, ensuring that the seismic upper connecting wall 4 and the seismic lower connecting wall 5 have a certain displacement space under the action of seismic loads. On both sides of the construction columns 2 are masonry secondary structures 6. The seismic upper connecting wall 4 and the seismic lower connecting wall 5 are connected to a connecting steel plate 8 through anchor bars 7, and the connecting steel plate 8 is connected through bolts and dog bone plates 9.

[0023] For the seismic wall provided by the present utility model, a foaming agent is filled in the reserved gap 3 to form a foaming filling area, and a wire mesh 10 is arranged in the foaming filling area for connection; to ensure that the foaming agent filling area does not crack during normal use, as Figure 2 shown.

[0024] The seismic wall provided by the present utility model consists of anchor bars 7, energy-dissipating connecting steel plates 8, and dog bone plates 9 to form a friction damper and a buckling restraint combined device. The energy-dissipating mechanism is as follows: Under the action of small earthquake loads, the first-order energy dissipation mainly offsets part of the seismic action through the friction between the bolts and the energy-dissipating connecting steel plate 8 and between the connecting steel plate 8 and the dog bone plate 9. Among them, the bolt holes 11 are oval-shaped to ensure sufficient displacement when the dog bone plate 9 slides, as Figure 3 and Figure 4 shown, Figure 3 where a is the top view of the connecting plate, b is the plan view of the connecting plate, and c is the side view of the connecting plate. The energy dissipation under large earthquake displacements mainly dissipates energy through the friction between the bolts and the connecting steel plate 8 and between the connecting steel plate 8 and the dog bone plate 9 and the buckling restraint deformation of the dog bone plate 9 together. Figure 3 is the structural schematic diagram of the connecting plate of the friction damper and the buckling restraint combined device of the present utility model

[0025] The seismic wall with a friction damper and a buckling restraint combined device provided by the present utility model has the following advantages:

[0026] 1. This friction damper and buckling restraint combined device can be prefabricated and processed in the factory and bolted on-site during construction, greatly improving the construction progress and having a high construction efficiency.

[0027] 2. For the friction damper and buckling-restrained combination device, through simulation and analysis by relevant software, the energy-dissipating component can withstand a horizontal load of approximately 100 t under minor earthquakes and 420 t under major earthquakes, and has good energy-dissipating capacity, which can effectively protect relevant components, such as Figure 5 as shown. In addition, the present utility model can achieve the purpose of replacement in the case of the failure of the buckling-restrained device.

[0028] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to that defined by the claims.
